Definitions

  • the present invention relates to a sealing device suitably used in a shaft seal part having a large shaft eccentricity or a large mounting eccentricity, for example, a dust seal or the like of a steering shaft in a vehicle such as a motor vehicle or the like, and more particularly to a sealing device with a sound insulating seal having a sound insulating function in addition to a sealing function.
  • the sealing device in accordance with the present invention is used in a general purpose machine or the like in addition to the vehicle mentioned above.
  • the sealing device 51 in Fig. 3 is constituted as a steering dust seal for a vehicle (refer to Fig. 5 described in patent document 1).
  • a seal body 56 sealing a clearance 55 between a peripheral surface 53a of a shaft hole 53 provided in a front dash panel 52 corresponding to a housing and a steering shaft 54 corresponding to a shaft inserted to the shaft hole 53, and a sound insulating seal 57 insulating a transmitted sound such as an engine sound transmitted to a passenger room inner side B from an engine room side A through the clearance 55, a traveling sound or the like is assembled in the seal body 56.
  • the seal body 56 has a mounting part 58 mounted to an inner periphery of the shaft hole 53 of the front dash panel 52, and a seal lip part 59 brought into contact with a peripheral surface of the steering shaft 54, and a bellows part 60 for responding to the shaft eccentricity or the like is integrally formed between the mounting part 58 and the seal lip part 59.
  • the sound insulating seal 57 has a sound insulating member 61 fixed to an inner peripheral side of the mounting part 58 of the seal body 56, and the sound insulating member 61 is formed, for example, in an annular shape by an elastic body.
  • the sealing device 51 mentioned above is structured such that the sound insulating member 61 of the sound insulating seal 57 arranged at the passenger room inner side B achieves a sound insulating function with respect to the transmitted sound transmitted through the bellows part 60 of the seal body 56 formed in a thin shape by an elastic body, thereby reducing a noise level at the passenger room inner side A, however, the following problems are generated with respect to the sound insulating performance which can be achieved thereby.
  • the sound insulating member 61 of the sound insulating seal 57 mentioned above is fixed to an inner peripheral side of the mounting part 58 of the seal body 56 in accordance with a fixing means or the like, and a large clearance (a diametrical clearance) 62 is set at a further inner peripheral side thereof, with respect to the steering shaft 54. Accordingly, the transmitted sound through the bellows part 60 mentioned above passes through the clearance 62 (as shown by an arrow C), whereby the achievable sound insulating performance is limited.
  • a sealing device 61 in which two seal bodies 62 each having a mounting part 63, a seal lip part 64 and a bellows part 65 are arranged side by side so as to form a bellows double structure, as shown in Fig. 4.
  • the sealing device 61 since the seal lip part 64 of the seal body 62 at a passenger room inner side A is brought into contact with a steering shaft and the clearance in the diametrical direction is not formed at an inner peripheral side thereof, it is possible to increase the sound insulating performance (refer to the patent document 1).
  • the present invention is made by taking the points mentioned above into consideration, and an object of the present invention is to provide a sealing device provided with both of the sealing function and the sound insulating function mentioned above, in which an excellent sound insulating performance can be achieved, and a length in an axial direction of the sealing device is not enlarged.
  • a sealing device with a sound insulating seal comprising:
  • a sealing device with a sound insulating seal as recited in the first aspect mentioned above, wherein the sound insulating member is supported by a lip-shaped sound insulating seal support part provided in the mounting part, is formed in a shape which interferes with the seal lip part, and has a structure such that a part of the sound insulating member is brought into close contact with the seal lip part in a state of being pressed by the seal lip part so as to be concaved.
  • the sound insulating member of the sound insulating seal is structured such as to be held to the seal body in the state of being brought into contact with the mounting part of the seal body at the outer peripheral part thereof and being brought into contact with the seal lip part of the same seal body at the inner peripheral part thereof, the clearance in the diametrical direction, which allows the transmitted sound to pass therethrough as in the prior art in Fig. 3 mentioned above, is not formed at the inner peripheral side of the sound insulating member. Further, since two bellows are not arranged side by side in the axial direction as in the prior art in Fig. 4 mentioned above, it is possible to prevent the length in the axial direction of the sealing device from being enlarged.
  • the sound insulating member is formed, for example, in an annular shape by an elastic body, and is attached to the inner peripheral side of the mounting part of the seal body.
  • the mounting means as described in the second aspect, it is preferable to be supported by the lip-shaped sound insulating seal support part provided in the mounting part, be formed in a shape interfering with the seal lip part, and have a structure such that a part of the sound insulating member is pressed by the seal lip part so as to be brought into close contact with the seal lip part in a state of being concaved.
  • the present invention achieves the following effects.
  • the sound insulating member is structured such as to be held to the seal body in the state of being brought into contact with the mounting part at the outer peripheral part thereof, and being brought into contact with the seal lip part at the inner peripheral part thereof as mentioned above, the clearance in the diametrical direction, which allows the transmitted sound to pass therethrough, is not formed at the inner peripheral side of the sound insulating member. Accordingly, since the sound insulating member completely closes the portion between the mounting part and the seal lip part so as to effectively absorb the transmitted sound, it is possible to improve the sound insulating performance.
  • the sound insulating member is brought into contact with the shaft constituted by a metal member, and there is a risk that an early fatigue such as a permanent deformation, an abrasion or the like is generated in some material of the sound insulating member.
  • the sound insulating member is brought into contact with the seal lip part constituted by the elastic body instead of the shaft. Therefore, it is possible to prevent the early fatigue from being generated in the sound insulating member.
  • the sealing device in accordance with the second aspect of the present invention since the sound insulating member is supported by the lip-shaped sound insulating seal support part provided in the mounting part, is formed in the shape which interferes with the seal lip part, and is structured such that a part of the sound insulating member is pressed by the seal lip part so as to be brought into close contact with the seal lip part in a state of being concaved, the clearance is hardly generated between the sound insulating member and the seal lip part. Accordingly, it is possible to improve the sound insulating performance from this point of view.
  • the present invention includes the following modes.
  • a sealing device in accordance with the present invention is formed in such a shape as to cover a bellows part by a sound insulating plate (a sound insulating member), or in such a shape as to cover the whole of the bellows part by the sound insulating plate, in order to achieve the object mentioned above. Further, in the case that a sound insulating plate retainer is provided for holding the sound insulating plate, it is possible to improve a sound insulating effect by reducing an inner diameter of the sound insulating plate retainer.

  • the sound insulating seal 7 insulates a transmitted sound such as an engine sound, a traveling sound and the like which is transmitted through the clearance 5 from an engine room side A to a passenger room inner side B.
  • the seal body 6 integrally has a mounting part 8 mounted to an inner periphery of the shaft hole 3 of the front dash panel 2, and a seal lip part 9 brought into contact with a peripheral surface of the steering shaft 4, and a bellows part 10 for responding to a shaft eccentricity or the like is integrally formed between the mounting part 8 and the seal lip part 9.
